BUG/MINOR: don't start haproxy on reload

If haproxy is not already running, reload should not start it.
Unfortunately the LSB spec does not explicitly cover this case:

  http://refspecs.linuxbase.org/LSB_3.1.1/LSB-Core-generic/LSB-Core-generic/iniscrptact.html

but it seems like the more correct behaviour, and actually fixes a
real-world issue we saw in SUSE Cloud.
